Mirror wiring

I bought after market tow mirrors for my 2018 tundra it was supposed to be plug and play all the functions work except my blind spot monitors and my rear traffic sensors does anyone know why?

 

Louis, search for the specific brand of mirrors you bought in the search bar. You will probably have to change the order of some of the pins in the connector, not difficult to do. Trick is finding where they have to go. Some manufacturers put them in different orders so you have to compare the pin maps and correct accordingly

 

I tried looking them up couldnt find anything I do know I'm missing pin 5 on the mirror side which should be a common ground which is also a shared ground with the blind spot monitors just not sure if i tapped into another ground and ran it to pin 5 on the truck side if that would help or not

 

I swapped pins 9 and 18 around and it got my bsm working now.

 

Did you swap them on the truck side or the mirror side bc i tried swapping 9 and 18 on the mirror side and it didn't work

 

I swapped them on the truck side
